Abstract
Magnetic moment measurements performed on a single crystal sample of (Tl,Pb)(Sr,Ba)2Ca2Cu3Oy reveal an increase in magneticmoment at intermediate fields. Magnetic hysteresis (m-H) loops were taken at different constant temperatures using either a MPMS-5T SQUID magnetometer or a PPMS-9T magnetometer and within the temperature range 0.1 < T/Tc < 0.85. Vortex dynamics at fieldsbelow the peak in hysteresis loops for the sample is shown to be well explained by a quasi-lattice Bragg glass state and elastic collectiv evortex creep.
